HTTP::Proxy::HeaderFilter::standard - An internal filter to respect RFC2616
This is an internal filter used by HTTP::Proxy to enforce behaviour compliant
with RFC 2616.
This filter implements a single method that is called automatically:
- filter()
- Enforce RFC 2616-compliant behaviour, by adding the
"Via:" and
"X-Forwarded-For:" headers (except when
the proxy was instructed not to add them), decrementing the
"Max-Forwards:" header and removing the
hop-by-hop and LWP::UserAgent headers.
Note that the filter will automatically remove the
"Accept-Encoding" headers if the proxy
has at least one HTTP::Proxy::BodyFilter filter. (This is to ensure that
the filters will receive uncompressed data.)

Thanks to Gisle Aas, for directions regarding the handling of the
hop-by-hop headers.
